EPA Lowers Ozone Standard
The EPA has lowered the ozone standard from 75ppb to 70ppb effective in 2018 based on a three year standard. This forces counties across the country to lower their ozone amounts as of January 1, 2016. If counties do not start to lower their ozone levels as of January 2016 they could face not having a low enough average over the three years to be complaint with the new 70ppb regulation. The new regulation states that any counties that are non compliant by 2018 will be placed on an unattainment list and could risk losing funding for their county.
This new regulation comes from a large nation-wide unattainment with smog still being a dominant air quality issue in many areas of the country. Smog, which is created by ground level ozone, causes many health risks to the population expecially young children, the elderly and persons with asthma. The American Lung Association has deemed smog one of the leading causes of asthma attacks in the United States.
